Natural astrology is confined to the study of exploring natural effects, in which sense it is admitted to be a part of natural philosophy. It was under this view that Mr. Goad, Mr. Boyle, and Dr. Mead, pleaded for its use. The first endeavours to account for the diversity of seasons from the situations, habitudes and motions of the planets: and to explain an infinity of phenomena by the contemplation of the stars. The Honourable Mr. Boyle admitted, that all physical bodies are influenced by the heavenly bodies; and Doctor Mead's opinion, in his treatise concerning the power of the sun and moon, etc. is in favour of the doctrine. But these predictions and influences are ridiculed and entirely exploded by the most esteemed modern philosophers, of which the reader may have a learned specimen in Rohault's, Tractat. Physic, part II. c. 27. The diseases of men, women, and children were supposed at times to be more immediately caused by the influence of the seven planets. In order to comprehend this exploded doctrine, we shall here set down the pretended governing and days, at what time they are supposed to have the most influence: [Symbol: Sol] Sol, or the sun governs on Sunday. [Symbol: Luna] Luna, or the moon, Monday. [Symbol: Mars] Mars, Tuesday. [Symbol: Mercury] Mercury, Wednesday. [Symbol: Jupiter] Jupiter, Thursday, [Symbol: Venus] Venus. Friday. [Symbol: Saturn] Saturn, Saturday. Saturn reigning, is said to cause cold diseases, as the gout, leprosy, palsy, quartan agues, dropsies, catarrhs, colds, rheumatisms, etc. Jupiter causes cramps, numbness, inflammations of the liver, head-aches, pains in the shoulders, flatulency, inflammatory fevers, and all diseases caused by putrefaction, apoplexy, and quinsies. Mars, acute fevers and tartan agues, continual and intermitting fevers, imposthumes, erisepelas, carbuncles, fistulas, dysentery, and similar hot and dry diseases. Sol causes rheums in the eyes, coldness in the stomach and liver, syncope, catarrhs, pustular eruptions, hysterics, eruptions on the lower extremities. Venus causes sores, lientery, hysteria, sickness at the stomach, from cold and moist causes, disorders of the liver and lungs. Mercury causes hoarseness and distempers in the senses, impediments in the speech, falling sickness, coughs, jaundice, vomiting, catarrhs. The moon causes palsy, cholic, dropsy, imposthumes, dysenteries, and all diseases arising from obstructed circulation.
